Ch. lunulata Swink. Similar to aurimargo (17 e) or still darker; scarcely any red on the yellow border. 
The most striking distinction is the long white cell-mark of the hindwing. Borneo (loc. typ.) and Selangor. lunulata,. 
Ch. tricolora B.-Balc. Forewing not quite so strongly bent as in lunulata , hindwing extraordinarily tricolora. 
elongate, the length from the (weak) apex to the strong prominence at 3rd radial - 1st median nearly as great 
as that of costa, the termen slightly sinuate on each side of the prominence. Tone somewhat orange (yellow 
densely mixed with purple-reddish); cell-mark of hindwing as in lunulata ; forewing with a curved, somewhat 
trilobed central yellow band from 1st radial to tornus; yellow of fringes encroaching on the wing in a few spots. 
Dinawa, British New Guinea, only the type $ known. 
Ch. flavisparsa Prout. The forewing has nearly the shape of the surrounding species; the hindwing flavisparsa. 
has the abdominal margin fairly long, the termen gibbous at the 3rd radial and 1st median, but not angled. 
The coloration is closely that of Ptockopkyle miniosa (mottled pink and yellow) but there are no definite mark¬ 
ings and no dark terminal line. Mount Goliath. 1 
Ch. elaeophragma Prout (17 f). Recognizable by the very extreme shape of the forewing, the browner elaeophrag- 
tone, rather strong markings, long white cell-streak of the hindwing, etc. Snow Mountains, a good series, very 
constant. 
Ch. uncimargo Warr. (17 f) also has the extraordinary forewing shape, if not, indeed, still further ex- uncimargo. 
aggerated. but is much larger, darker, more indefinitely marked, with a yellow spot at tornus of forewing and 
apex of hindwing; the hindwing, moreover, is remarkably produced. British and Dutch New Guinea the type 
from Biagi. 
Ch. plumbeofusa Swink. (17 f). Markings weak, excepting the black cell-sjoot of the forewing; shape plumbeofusa. 
simple, the extremely curved postmedian line of the forewing suggesting a possible association with the first 
few species of the genus as here arranged; but the long pectinations of the $ antenna refer it to the following 
group. Khasis and (perhaps in a separable race with smaller cell-spot) Singapore. 
Ch. semiocellata Prout is only known from the type $ (Snow Mountains, near Oetakwa River), but semiocellata. 
its general similarity to concentrica (17 g), especially in the extreme curvature of the lines of the forewing, 
leads one to suppose that the $ will have strongly bipectinate antenna. Possibly even a subspecies. Much 
darker — heavily irrorated and strigulated with black - - but with the gold-yellow of the fringes encroaching 
a little further on to the wings; lines thicker, the postmedian of the hindwing more sinuous; cell-dot of hind¬ 
wing enclosed in a thick black ring. 
Ch. altegradia Prout is mother near relative or possible race of concentrica. Larger (about 30 mm), altegradia. 
both distal margins slightly less curved; lines obsolete; yellow of fringes scarcely invading the wings; terminal 
shade narrower than in the name-type of concentrica, but broader than in ab. lineimargo; a slightly paler area, 
about 2.5—3 mm wide, between this border and the rest of the ground-colour. A $ from Klondyke, Benguet, 
Luzon. 
Ch. concentrica Warr. (17 g). Variable, but generally easy to recognize by its shape and structure, concentrica. 
notably in the $, with its very long antennal pectinations. The type, a from St. Aignan. has the dark bor¬ 
ders slightly broader than in the figured <$, which comes from Kumusi River, British New Guinea. — ab. linei- lineimargo. 
margo ab. nov. lacks the dark marginal shade, which is merely represented by a line, usually of a redder tone. 
The type is a from Kumusi River, but it represents the commoner form of the species and occurs in both 
sexes. — ab. regalis Warr., mistaken by its author for a $ and therefore assumed to be a separate species, is regalis. 
a large $ from St. Aignan with the lines obsolete, the marginal shades present, though neither so broad nor 
so dark as in the type. Like most $$ it has a more reddish tone than the typical <$<$, but the colour differences 
are inconstant, concentrica is distributed in the islands off New Guinea (rarer on the mainland), especially the 
Louisiades and the Bismareks, and reaches Choiseul and Guizo. 
Ch. indopurpurea Prout (17 g) differs from concentrica in its strongly bent hindwing, duller colour and indopurpu- 
weaker markings. Snow Mountains (type) and British New Guinea. rea - 
Ch. flavimedia Prout (17 g). In shape intermediate between the two preceding, the hindwing more flavimedia. 
nearly as in the latter of them. Cell-mark of hindwing elongate, red-brownish, indistinct; the yellow central 
patches recall dinawa more than any other known Chrysocraspeda. $ antenna strongly bipectinate. Near 
Oetakwa River, Snow Mountains. — ab. perspersa Prout, has the cell-spots rather less long but broader, the perspersa. 
median yellow patches much reduced, the rest of the wing, right to the termen, almost evenly irrorated with 
the darker colour. 1 taken with the type form. Possibly a separate species. — panconita subsp. nov. (17 g) panconita. 
lacks entirely the yellow median patch, has the whole wing-surface densely but finely irrorated, the markings
